Thomas Neidhart reopened COLLECTIONS-318:
-----------------------------------------
> CollectionUtils.size(Object object) has impossible null check
> -------------------------------------------------------------
>
> Key: COLLECTIONS-318
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-318
> Project: Commons Collections
> Issue Type: Bug
> Components: Collection
> Reporter: Sebb
> Priority: Minor
> Fix For: 4.0
>
>
> CollectionUtils.size(Object object) has impossible null check:
> {code}
> public static int size(Object object) {
> if (object == null) {
> return 0;
> }
> ...
> } else if (object == null) {
> throw new IllegalArgumentException("Unsupported object type:
> null");
> ...
> {code}
> The Javadoc specifically says that null is allowed, so I think the object ==
> null clause needs to be removed - it can never be true, and is just confusing.
